Question

I have a tough scenario I’m trying to debug… On a web forms page, when I click submit, the web server hits some error and restarts the w3svc process.

I do not see any stack trace dumped to the event log. The only entry in the Windows Application Log is:

Faulting application name: w3wp.exe, version: 7.5.7600.16385, time stamp: 0x4a5bd0eb

Faulting module name: KERNELBASE.dll, version: 6.1.7600.16385, time stamp: 0x4a5bdfe0

Exception code: 0xe053534f

There is no mini dump created for me to attach windbg to…

Any ideas how to debug my issue?

Answer 1

I suspect that you make a loop call like

public string sMyText
{
   get {return sMyText;}
   set {sMyText = value;}
} 

and you call the sMyText

or something like

protected override void OnLoad(EventArgs e)
{
  base.OnInit(e);
}

or something like

Server.Transfer("TheSamePage.aspx");

In this cases the crash is not call the minidump.
Can you run the process explorer and see if your pool is eat the cpu until is crash ?
